ABSTRACT:
A data input/output management scheme suitable for protection of electronic writing data. Whether the data entered into the program is a protected data or not is judged, and when it is, at least the identifier for identifying the program is recorded as the protected data input record. Then, a data output is permitted when the identifier for identifying the program is not recorded in the protected data input record, while whether or not to permit a data output is judged according to at least a requested output target when the identifier for identifying the program is recorded in the protected data input record. For the writing data, the application program is authenticated, and the authentication result is stored in correspondence to an identifier for identifying the application program. Then, a request for access to writing data from the application program is permitted when the stored authentication result for the application program indicates a successful authentication for the application program.
